ANVlL-SHEARS FOR CUTTING METAL.

SPECIFICATION forming part of Letters Patent No. 403,980, dated May 28, 1889.

Application filed March 11, 1889. Serial No. 302,937. (No model.)

To all whom it may concern.-

Be it known that I, WILLIAM HINYARD ADAMS, a citizen of the United States, residing at Franklin, in the parish of St. Marys and State of Louisiana, have invented certain new and useful Improvements in Anvil-Shears for Cutting Metal; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable IO others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form part of this specification.

My invention relates to shears for cutting iron and steel, and has for its object to provide an instrument so constructed that it can be readily applied to or detached from an anvil and be at hand for ready use at the side thereof. Its further object is to provide substantial means for guiding and holding the movable cutter-bar in a true position so that its edge will work closely by the side of the stationary cutter-bar, in order that the'shears may produce a clear straight out without bending the edge of heavy sheet metal or leaving burrs on the edge of thick bars or bolts, and also in arranging-the parts in such a manner as to get the strongest possible leverage upon the movable cutter, to enable the shears to be used in cutting bolts and other bars of medium-sized iron with ease; and it consists in the construction hereinafter described, and more particularly pointed out in the claims.

3 5 Referring to the drawings, Figure 1 is a perspective view of my improved shears applied to an anvil. Fig. 2 is a side view of the shears removed from the anvil. Fig. 3 is a detail top view of the stationary cutter-bar.

Fig. 4 is an edge view of the connecting-link between the movable cutter and lever, and

Fig. 5 is a modified form of the same.

Like letters of reference refer to corresponding parts in each figure of the drawings.

A represents the old and well-known form of anvil employed by blacksmiths, having the usual vertical square hole or opening, a, in one end of its upper face, for inserting Various tools, in which my device is secured.

The stationary cutter B of the shears is ting small articles.

made of hardened steel, and its under surface is formed flat and of a length to reach across the end of the face of an anvil. On one side of the cutter there is a vertical holding-pin,

I), made integral with the cutter, or it maybe welded or otherwise secured thereto, as desired, which fits in the hole aof the anvil and holds the cutter in position thereon.

From the end of the stationary cutter-bar B nearest to the operator, and integral therewith, extends outward and downward at an obtuse angle an arm, 0, upon the outer side of which at cthere is closely pivoted a guidebar, D, which is bent outward from the arm at a short distance above its attachment, and then upward parallel to and on the same angle with the arm to some distance above the upper edge of the stationary cutter-bar B, leaving a space between the arm 0 and guidebar D just equal to the thickness of the mov- 7o able cutter. The guide-bar D, while ordinarily used when at the same angle as the arm C, may be adjusted or turned forward on the pivot 0, so that its upper portion will come in contact with the movable cutter-bar nearer its front pivotal point with the lower one, to hold the two cutting-edges in contact in out By this construction of guide-bar the movable cutter is kept in a true position relative to the stationary one, and is prevented from springing away from it in operation and bending or leaving burrs on the out edge of the metal.

Near the front end of the stationary cutterbar B, and 011 the opposite side of the anvil from the operator, the bar is bent upon itself at (Z, bringing the end parallel with the body of the cutter, leaving a space between them.

The movable or upper cutter-bar, E, is bent near one end, forming a short arm, 6, at an obtuse angle to the main bar, as shown in dotted lines in Fig. 2. This short arm 6 is pivotally secured between the main bar B and its bent end d, which form bearings for the journal, holding it in place. The movable 5 cutter-bar E is formed of the same material as the stationary cutter, and is made to extend some distance back of the vertical plane of the end of the arm O and rest between the stationary cutter-bar B and the guide-bar D. zoo

To the lower end of the obtuse-angle arm 0 there is pivoted at f a lever, F, that extends back some distance in the rear of the end of the cutter-bar E. At a suitable distance back of the pivotal point f on the lever, and about on avert ical plane with the rear end of the movable cutter E, there is a connecting-link, G, pivoted to the lever, and extending upward is also pivoted to the rear end of the upper cutter-bar, E, thereby uniting and holding the parts in a steady and relative position one to the other. The link G is formed of two strips of metal laid side by side and secured in the center by a rivet or bolt, 9, having their endsH bent outward and extending parallel to each other and a sufficient distance apart to admit the lever and end of the cut- E, i. wh c h e p ted.

U I do not wish to limit myself, however, to

this particular form of link, as it may he made of a single bar having slotted ends, as shown in Fig.5, of the drawings, or in anyother coiiyenientforin, in order to accomplish the same Pu p I, h .t

V In connecting the different parts of my shearsto ether informing the pivotal points Int: 1 1 s n u that th rartsm y be readily detached, though I do not wish to confinemyself to their especial employmenaas rivets inaybe used', if desired, and the parts permanently fastened together.

Having thus fully described my. invention, what I claim as new, and, desire to secure by Letters Patent of the United States, is

1. Shears for cutting metal having a stationary cutter-bar, one end of said bar being extended to form an arm at an obtuse angle to the cutter, said arm having an adjustable guide-bar pivoted to its side and a lever to its end, the other end of the bar having a movable cutter pivoted thereto, and a link connecting the other end of the movable cutter and the lever, as set forth.

2.4 The combination, witha stationary cutter-bar having a pin in its center adapted to be held iii aii anvil, of an arm extending at an obtuse angle downward from the end of the bar, a lever pivoted to the end of the arm, and an adjustable guide-bar secured tothe side of thearm and bent outward and'extending parallel thereto; the op os'ite end of the stationary cutter bar benv upon itself, forming a pivotal bearing for one end of the movable cutter-bar; theopposite end of the movable cutter connected to the lever by a link, as set forth. 7 Z p In testimojny whereof I affix my signature in presence of, two witnesses.
